Landscape timber connector

ABSTRACT

A landscape connector is adapted for coupling respective proximal ends of adjacent landscape timbers. The landscape connector includes spaced-apart opposing top and bottom walls and opposing side walls. The top and bottom walls define respective flat outside surfaces of the landscape connector. The side walls are formed with the top and bottom walls, and define respective outwardly bowed inside surfaces of the landscape connector. The top, bottom, and side walls cooperate to form a stable housing having first and second open ends adapted for receiving respective proximal ends of the adjacent landscape timbers.

TECHNICAL FIELD AND BACKGROUND OF THE INVENTION

The present invention relates to a landscape connector applicable for coupling respective proximal ends of adjacent landscape timbers.

Landscape timbers are a popular and common “hardscape” in many residential properties, adding a woodsy and practical accent to the yard, garden, or playground. Such timbers are relatively lightweight and have two opposing flat sides allowing them to be easily stacked. While most timbers are composed of new wood, others are manufactured of recycled plastics. In either case, the timbers are relatively uniform and smooth making them excellent for stair steps and retaining walls. Other popular applications include flower-bed borders, walkway, patio, and driveway curbs, garden beds, pond enclosures, sandboxes, and decorative walls. Landscape timbers are available in a full range of sizes—from 4″×4′ to 12″×12′.

When stacking timbers, particularly above 2-3 courses, in order to stabilize the landscape structure, a number of 10″ galvanized spikes are typically hammered through overlapping ends using a sledge hammer. This process is both labor intensive and time consuming, and in many cases damages the timber or detracts from the overall aesthetic appearance of the landscape structure. Any protrusion of the spikes above or beyond the timber may also present a substantial safety hazzard. For single course structures, the timbers are generally arranged end-to-end around a designated perimeter. In playgrounds and other high traffic areas, the timbers are often inadvertently kicked out of place, creating a rather disheveled appearance in the landscaping.

SUMMARY OF INVENTION

Therefore, it is an object of the invention to provide a landscape connector which safely and securely interconnects adjacent timbers.

It is another object of the invention to provide a landscape connector which is relatively inexpensive to manufacture.

It is another object of the invention to provide a landscape connector which is applicable for effectively interconnecting multiple stacked timbers in adjacent sets of timbers.

It is another object of the invention to provide a method of interconnecting respective proximal ends of adjacent landscape timbers.

These and other objects of the present invention are achieved in the preferred embodiments disclosed below by providing a landscape connector adapted for coupling respective proximal ends of adjacent landscape timbers. The landscape connector includes spaced-apart opposing top and bottom walls and opposing side walls. The top and bottom walls define respective flat outside surfaces of the landscape connector. The side walls are formed with the top and bottom walls, and define respective outwardly bowed inside surfaces of the landscape connector. The top, bottom, and side walls cooperate to form a stable housing having first and second open ends adapted for receiving respective proximal ends of the adjacent landscape timbers.

The term “timber” is used broadly herein to describe any cut wood or other material suitable for use in a landscape structure.

According to another preferred embodiment of the invention, the first and second open ends of the housing are located in substantial linear alignment.

According to another preferred embodiment of the invention, a first intermediate wall is formed between and parallel to the top and bottom walls of the housing. Each of the first and second open ends is thus adapted for receiving respective proximal ends of two stacked timbers.

According to another preferred embodiment of the invention, a second intermediate wall is formed parallel to the first intermediate wall and between the top and bottom walls of the housing. Each of the first and second open ends is thus adapted for receiving respective proximal ends of three stacked timbers.

According to another preferred embodiment of the invention, means are provided for mechanically attaching the housing to respective proximal ends of the adjacent landscape timbers.

According to another preferred embodiment of the invention, the means for mechanically attaching includes a fastener selected from a group consisting of nails, screws, bolts, rivets, and staples. Other means for attaching may include a narrow elastic or nylon belt tightly wrapped around an outside of the housing, an adhesive, or simple friction fit.

According to another preferred embodiment of the invention, at least one of the top, bottom, and side walls of the housing defines at least one fastener opening adapted for receiving the mechanical fastener.

In another embodiment, the invention is a method for coupling respective proximal ends of adjacent landscape timbers. The method includes the steps of inserting a proximal end of a first landscape timber into an open end of a multi-wall landscape connector. A proximal end of an adjacent landscape timber is then inserted into a second open end of the landscape connector.

According to another preferred embodiment of the invention, the method further includes mechanically attaching the landscape connector to respective proximal ends of the adjacent landscape timbers.
